My experience with a private purchase of a fifth wheel in California (Oct 2008):
Drove to suburban San Diego to complete the purchase and bring the trailer back to Florida. The owner accompanied me to the Poway DMV office to complete the sale(he kept his tag as he had a new trailer on order). We did the requisite sale paperwork and I asked the DMV clerk about temporary tag. Was told there is no such thing and when all was said and done, paid $2500 for "use tax", title application, registration and California tag.
When I returned to Florida to apply for Florida registration and title, I was refunded the difference between Florida sales tax I would have paid and the California "use tax" I was charged. And the $230 registration/tag from California was replace with a $56 Florida tag/registration.
